我正在尝试在 CircleCI 上运行需要pytest-qt(用于测试 PySide2 对话框)的测试。我收到以下错误:

xdpyinfo was not found, X start can not be checked! Please install xdpyinfo!

我正在使用这个配置文件:

          path: test-reports
      - run:

          command: coveralls

非常感谢任何帮助,在此先感谢。

我已经在circleci/python:3.6.8-stretch本地提取了容器,克隆了您的存储库并尝试执行测试,而我可以重现错误。

首先要做的是启用 Qt 运行时的调试模式,以便打印一些有关错误的信息。这可以通过设置环境变量来完成QT_DEBUG_PLUGINS

$ QT_DEBUG_PLUGINS=1 pytest -sv

现在可以立即清楚容器中缺少什么来运行测试。上述命令输出的片段:

Got keys from plugin meta data ("xcb")
QFactoryLoader::QFactoryLoader() checking directory path "/usr/local/bin/platforms" ...
Cannot load library /home/circleci/.local/lib/python3.6/site-packages/PySide2/Qt/plugins/platforms/libqxcb.so: (libxkbcommon-x11.so.0: cannot open shared object file: No such file or directory)
QLibraryPrivate::loadPlugin failed on "/home/circleci/.local/lib/python3.6/site-packages/PySide2/Qt/plugins/platforms/libqxcb.so" : "Cannot load library /home/circleci/.local/lib/python3.6/site-packages/PySide2/Qt/plugins/platforms/libqxcb.so: (libxkbcommon-x11.so.0: cannot open shared object file: No such file or directory)"
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.

Aborted (core dumped)

解决这个问题很简单 - 安装libxkbcommon-x11-0软件包:

$ sudo apt update && sudo apt install -y libxkbcommon-x11-0

在 CircleCI 配置中添加这一行(在测试作业之前的某个位置,例如在安装包依赖项的作业中),测试应该可以正常运行。

除此之外,全局设置是有意义的,QT_DEBUG_PLUGINS=1这样您就可以在将来对最终的 Qt 运行时故障做出反应。

没有找到xdpyinfo,无法检查X start!请安装 xdpyinfo!

如果您想摆脱该警告,请安装x11-utils

$ sudo apt install x11-utils

Centos6.5只运行:yum install xdpyinfo,成功解决
